Description

Technical Field

[0001] This utility model relates to the field of flame-retardant sheet technology, and in particular to a flame-retardant sheet curing treatment device. Background Technology

[0002] Flame-retardant sheets are a type of engineered plywood with good barrier properties and difficult combustion. They are produced by adding flame retardants to the sheets through a complex process.

[0003] After the flame-retardant sheets are processed and formed, they need to be cured so that the adhesive and other materials are dried and cured and no longer deformed. Some flame-retardant sheet curing equipment often has problems such as small curing quantity and low production efficiency. In addition, the drying effect of the flame-retardant sheets is uneven during the drying and curing process, requiring a longer curing time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flame-retardant sheet curing treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flame-retardant sheet curing device includes a curing chamber and a slider. The curing chamber is a hollow cylindrical structure. A central shaft is rotatably connected to the center of the curing chamber. An air duct extending to the bottom of the central shaft is opened at the top of the central shaft. Several air holes communicating with the air duct are evenly opened on the side wall of the central shaft. Three evenly distributed first mounting plates are fixedly connected to the top of the central shaft, and three evenly distributed second mounting plates are fixedly connected to the bottom of the central shaft. Connecting columns are fixedly connected around the opposite sides of the first and second mounting plates. Three evenly distributed fixing blocks are fixedly connected to each connecting column. A fixed slide rail is fixedly connected between two adjacent fixing blocks at the same vertical height below each first mounting plate. Two electric heating tubes intersecting with the fixed slide rail are fixedly connected to the side wall of the four connecting columns below each first mounting plate. A slider is slidably connected inside the fixed slide rail. A connecting rod is fixedly connected to one end of the two sliders at the same vertical height below each first mounting plate near the central shaft. Several evenly distributed fixing teeth are fixedly connected to one side of the bottom of the slider. A pressure plate is slidably connected to the middle of the slider above the fixing teeth.

[0007] Preferably, the curing chamber has an outlet on one side, an outlet door is rotatably installed at the outlet, a controller is fixedly installed on the outer wall of the outlet door, and a door handle is fixedly installed on one side of the outlet door.

[0008] Preferably, a filter screen is installed at the top of the central shaft, and a fan is fixedly installed at the top of the curing chamber. The outlet end of the fan is connected to the air duct at the top of the central shaft through a pipe.

[0009] Preferably, a motor is fixedly installed at the bottom of the curing chamber, the output shaft of the motor passes through the bottom of the curing chamber, and the end of the output shaft of the motor is fixedly connected to the bottom of the central shaft.

[0010] Preferably, the length of the fixed slide rail is greater than the length of the slider, and limit strips are symmetrically arranged on the top and bottom inner walls of the fixed slide rail, and limit grooves are opened at the top and bottom of the slider to slide and connect with the limit strips.

[0011] Preferably, heating elements are fixedly installed at the bottom of the first mounting plate and the top of the second mounting plate, and a hanging ring is fixedly connected to the end of the slider away from the central axis.

[0012] Preferably, the pressure plate is rotatably connected to a screw threaded to the slider on the side away from the fixed teeth. The end of the screw has a hexagonal recessed groove, and the sum of the length of the screw and the thickness of the pressure plate is equal to the thickness of the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting a first mounting plate and a second mounting plate, installs three sets of first mounting plates and second mounting plates in a circular curing chamber. The three sets have the same structure, which greatly increases the number of flame-retardant sheets that can be cured in the curing chamber, thereby improving the curing efficiency through centralized processing.

[0015] This invention features a central shaft that rotates three sets of first and second mounting plates. During loading and unloading, each set of first and second mounting plates can be rotated to the outlet door, facilitating the loading and unloading of flame-retardant sheets. An air duct at the center of the central shaft allows air to be blown through air holes onto the flame-retardant sheets being cured. The combination of air blowing and heating by the electric heating element accelerates curing. The airflow into the curing chamber also pressurizes the interior, further enhancing the curing effect. After curing, when the heating element stops heating and the outlet door is opened for heat dissipation, the fan continues to blow air to quickly dissipate the heat inside the curing chamber, accelerating the cooling of the flame-retardant sheets and improving work efficiency.

[0016] This invention uses a slider and an electric heating element. Two sliders at the same height slide synchronously through a connecting rod, and the fixed teeth support both sides of the flame-retardant sheet, allowing the flame-retardant sheet to be suspended. This means that the flame-retardant sheet can be evenly heated from both the top and bottom by the electric heating element. The pressure plate can press and fix both sides of the flame-retardant sheet, preventing the flame-retardant sheet from sliding during loading and unloading or due to air blowing, thus reducing the damage rate of the flame-retardant sheet.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7A flame-retardant sheet curing device includes a curing chamber 1 and a slider 11. The curing chamber 1 is a hollow cylindrical structure. A central shaft 2 is rotatably connected to the center of the curing chamber 1. An air duct extending to the bottom of the central shaft 2 is opened at the top of the central shaft 2. Several air holes 4 connected to the air duct are evenly opened on the side wall of the central shaft 2. Three evenly distributed first mounting plates 6 are fixedly connected to the top of the central shaft 2. Three evenly distributed second mounting plates 61 are fixedly connected to the bottom of the central shaft 2. Connecting columns 7 are fixedly connected around the opposite sides of the first mounting plates 6 and the second mounting plates 61. Three evenly distributed connecting columns 7 are fixedly connected to each connecting column 7. The fixed blocks 8 are distributed. A fixed slide rail 9 is fixedly connected between two adjacent fixed blocks 8 at the same vertical height below each first mounting plate 6. Two electric heating tubes 71 that intersect with the fixed slide rail 9 are fixedly connected to the side walls of the four connecting columns 7 below each first mounting plate 6. A slider 11 is slidably connected inside the fixed slide rail 9. A connecting rod 91 is fixedly connected to one end of two sliders 11 at the same vertical height below each first mounting plate 6 near the central axis 2. Several evenly distributed fixed teeth 13 are fixedly connected to one side of the bottom of the slider 11. A pressure plate 14 is slidably connected to the middle of the slider 11 above the fixed teeth 13. Three sets of first mounting plates 6 and second mounting plates 61 are installed in the circular curing chamber 1. These three sets have identical structures, significantly increasing the number of flame-retardant sheets that can be cured in the chamber. This centralized processing method improves curing efficiency. The rotation of the central shaft 2 drives the three sets of first mounting plates 6 and second mounting plates 61 to rotate to the outlet door 101 during loading and unloading, facilitating the loading and unloading of flame-retardant sheets. An air duct is located in the center of the central shaft 2, allowing air to be blown by the fan 51 through the air holes 4 onto the flame-retardant sheets being cured. The combination of this airflow and the heating element 71 accelerates curing. Furthermore, the airflow into the curing chamber 1 can also be used to treat the internal components of the chamber. Pressurization and increased pressure also help improve the curing effect. After curing, when the heating element 71 stops heating and the outlet door 101 is opened for heat dissipation, the fan 51 continues to blow air to dissipate the heat inside the curing chamber 1 as quickly as possible, which can accelerate the cooling of the flame-retardant sheet and also help improve work efficiency. Every two sliders 11 at the same height slide synchronously through the connecting rod 91 and support both sides of the flame-retardant sheet through the fixing teeth 13, so that the flame-retardant sheet is suspended, that is, the upper and lower parts of the flame-retardant sheet can be evenly heated by the heating element 71. The pressure plate 14 can press and fix both sides of the flame-retardant sheet, which can prevent the flame-retardant sheet from sliding during loading and unloading or due to air blowing, and reduce the damage rate of the flame-retardant sheet.

[0027] As a technical optimization of this utility model, an outlet is provided on one side of the curing chamber 1, and an outlet door 101 is rotatably installed at the outlet. A controller 102 is fixedly installed on the outer wall of the outlet door 101, and a door handle is fixedly installed on one side of the outlet door 101. The controller 102 is used to control the working temperature of the heating element 71 and the air pressure of the fan 51, and to control the rotation of the motor 5 during loading and unloading.

[0028] As a technical optimization of this utility model, a filter screen 3 is installed at the top of the central shaft 2, and a fan 51 is fixedly installed at the top of the curing chamber 1. The outlet end of the fan 51 is connected to the air duct at the top of the central shaft 2 through a pipe. The filter screen 3 can filter the air blown into the curing chamber 1 by the fan 51, which can reduce the adhesion of impurities on the outer surface of the flame-retardant sheet, making the finished flame-retardant sheet more aesthetically pleasing.

[0029] As a technical optimization of this utility model, a motor 5 is fixedly installed at the bottom of the curing chamber 1. The output shaft of the motor 5 passes through the bottom of the curing chamber 1, and the end of the output shaft of the motor 5 is fixedly connected to the bottom of the central shaft 2. During the loading and unloading stage, by controlling the rotation of the motor 5 to drive the central shaft 2 to rotate, the three sets of first mounting plates 6 and second mounting plates 61 can be rotated sequentially to the outlet door 101, thereby facilitating the loading and unloading of flame-retardant sheets by the staff.

[0030] As a technical optimization of this utility model, the length of the fixed slide rail 9 is greater than the length of the slider 11. Limiting strips 10 are symmetrically arranged on the top and bottom inner walls of the fixed slide rail 9. Limiting grooves that slide and connect slidably with the limiting strips 10 are provided at the top and bottom of the slider 11. The slider 11 slides stably in the fixed slide rail 9 without falling off due to the limiting strips 10. The greater length of the fixed slide rail 9 compared to the slider 11 facilitates the sliding of more of the slider 11 out of the outlet door 101 during loading and unloading, making it easier for operators to handle.

[0031] As a technical optimization of this utility model, heating tubes 71 are fixedly installed at the bottom of the first mounting plate 6 and the top of the second mounting plate 61, and a hanging ring 12 is fixedly connected to the end of the slider 11 away from the central axis 2. The heating tubes 71 at the bottom of the first mounting plate 6 and the top of the second mounting plate 61 ensure that the top and bottom of the flame-retardant sheets above and below can also be fully heated and dried. The hanging ring 12 makes it easy for workers to use a hook to pull out the slider 11 and prevent burns.

[0032] As a technical optimization of this utility model, a screw 15, threadedly connected to the slider 11, is rotatably connected to the side of the pressure plate 14 away from the fixing teeth 13. A hexagonal recessed groove 16 is formed at the end of the screw 15, and the sum of the length of the screw 15 and the thickness of the pressure plate 14 is equal to the thickness of the slider 11. When the flame-retardant sheet is placed on the tops of the fixing teeth 13 of the two opposing sliders 11, an Allen wrench can be inserted into the recessed groove 16 and the screw 15 rotated to cause the pressure plate 14 to press against the sidewall of the flame-retardant sheet, thereby fixing the flame-retardant sheet.

[0033] In use, this invention first uses a hook to pull the slider 11 to the end of the fixed slide rail 9. Then, a flame-retardant sheet is placed on the top of the fixing teeth 13 of the two opposing sliders 11. An Allen wrench is inserted into the recessed groove 16, and the screw 15 is rotated to cause the pressure plate 14 to press against the side wall of the flame-retardant sheet. The other pressure plate 14 is operated in the same way to fix the flame-retardant sheet. The slider 11 is then pushed, causing it to slide the flame-retardant sheet to near one end of the fixed slide rail 9, close to the central shaft 2. The above operation is repeated to place two more flame-retardant sheets. After placement, the controller 102 controls the motor 5 to rotate the central shaft 2 by 120 degrees, thus allowing the other set of first mounting plates 6 and second mounting plates to rotate. Rotate 61 to the outlet door 101, repeat the above operation to place the flame-retardant sheet, and control the motor 5 to drive the central shaft 2 to rotate 120 degrees again through the controller 102, so that the third set of first mounting plate 6 and second mounting plate 61 can rotate to the outlet door 101. Repeat the placement operation again. At this time, the flame-retardant sheet is placed. Close the outlet door 101, use the controller 102 to set the working temperature and working time of the electric heating tube 71 to heat and dry the flame-retardant sheet, and start the fan 51 and set the air pressure of the fan 51. The fan 51 blows air through the air duct and air hole 4 to the flame-retardant sheet being cured. The filter screen 3 can filter the impurities in the air blown into the curing chamber 1 by the fan 51.

[0034] Once the curing time is reached, the heating element 71 stops working, the outlet door 101 is opened, and the fan 51 continues to blow air to dissipate the heat inside the curing chamber 1 as quickly as possible, which can accelerate the cooling of the flame-retardant sheet. After cooling, the staff uses a hook to hook the slider 11 out through the hanging ring 12, and reverses the screw 15 to make the pressure plate 14 separate from the side wall of the flame-retardant sheet. The flame-retardant sheets are removed one by one, and the flame-retardant sheets between the three sets of first mounting plates 6 and second mounting plates 61 are removed one by one by controlling the motor 5 to drive the central shaft 2 to reverse 120.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
